As the pug mill mixer operates on a continuous feed basis rather than as a batch process, there was a need to continuously obtain feedback on the output. Intensive monitoring of the initial six lifts resulted in further changes to the mix design as shown in Figure 6. The grading was modified to reduce the sand content outside of the specified

Learn MoreTesting Concrete Mix Ratio . The design strength of concrete is the strength after 30 days of curing. Concrete normally reaches 50% of its design strength after 7 days and 75% after 21 days. Concrete is normally tested at 7 days and 30 days. The 7 days test will give an idea of the full strength of the concrete.

Learn MoreWhen making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mix. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.

Learn MoreThe pugmill mixer is referred to as a continuous flow plant since materials are fed into the mixer at the same rate that RCC is discharged out of the mixer. Continuous flow plants have total mixing times on the order of 10-30 seconds and can produce large amounts …
